java - Spring 3.1 entityManagerFactory java.lang.NoSuchFieldError : NULL Error

Question

我刚刚将 Spring 3.0.5 迁移到 3.1 GA。我在初始化期间遇到了运行时错误:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor#0': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in ServletContext resource [/WEB-INF/spring/infrastructure-config.xml]: Initialization of bean failed; nested exception is java.lang.NoSuchFieldError: NULL

这是我的 xml。

<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
    <property name="persistenceUnitName" value="MyPersistenceUnit" />
  </bean>

这个 java.lang.NoSuchFieldError: NULL 是关于什么的？ 3.0.5 没有问题。

这意味着存在版本不匹配——很可能是 spring 类。所以确保你所有的 spring jar 都是 3.1.0。特别是 spring-expression。 (如果在修复 spring 后它不起作用，还升级您的 JPA 提供程序( hibernate ？))
